Title:
DRAGGING PREVENTION DEVICE FOR SHIP ANCHOR CABLE IN SPRING RANGE ENVIRONMENT, AND DRAGGING PREVENTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/012025
Kind Code:
A1
Abstract:
A dragging prevention device for a ship anchor cable in a spring range environment, and a dragging prevention method therefor. The dragging prevention device comprises a base plate (1), wherein a chain wheel support (2) is welded above a front side of the base plate (1), a chain cable fairlead (3) for guiding an anchor chain is adapted to a front end of the chain wheel support (2), a mooring cable angle monitoring assembly is provided below the front side of the base plate (1), and the mooring cable angle monitoring assembly comprises a first bracket (701), a second bracket (702) and a chain guide cylinder seat (703). A deflection angle of a rotating shaft A connected between the second bracket (702) and the first bracket (701) is monitored by a first angle encoder (7021), and a deflection angle of a rotating shaft B connected between the second bracket (702) and the guide chain cylinder seat (703) is monitored by a second angle encoder (7031), such that the deflection angles of the anchor chain (4) in two directions can be obtained. If the angle of the anchor chain is not changed for a long time or the change in the angle is small, a data processing chip sends an early dragging warning to a central control of a mooring ship in this case, and the determination of dragging is accurate.
